This error occurred on Xcode 12 in a fairly empty sample project with only the default unit tests (no code coverage). I was using this project to test my fastlane file and CI/CD setup in Azure DevOps Microsoft hosted Mac agent (10.15)

My fastlane lane:

  lane :test do |options|
    parameter_validation(options)

    project = options[:project_name]
    scheme = project + (options[:is_library] ? "Sample" : "")

    scan(
      scheme: scheme,
      output_directory: "./sonar-reports",
      output_types: "html,junit,json-compilation-database",
      output_files: "TEST-report.html,TEST-report.xml,compile_commands.json",
      code_coverage: true,
      clean: true,
      skip_build: true,
      derived_data_path: "Build"
    )

    coverage_files_to_ignore = [
      '../../*',
      'Pods/*',
      '*Sample/*',
      '*Tests.m',
    ]

    swiftlint(
      output_file: "./sonar-reports/swiftlint.json",
      reporter: "json",
      ignore_exit_status: true,
      config_file: '.swiftlint.yml'
    )

    slather(
      scheme: scheme,
      sonarqube_xml: true,
      output_directory: "sonar-reports",
      proj: project + ".xcodeproj",
      workspace: project + ".xcworkspace",
      ignore: coverage_files_to_ignore,
      build_directory: "/"
    )
  end
